This invention relates to fa'stening means for securing covers on boxesand the like and more particularly for securing the trm on a panel boardcabinet or boxes. The fastening means is of the kind shown in GreavesPatent No. 1,287,000 issued December '10,:

' 1918. i i v i The invention consists in the novel features ofConstruction whereby the cost* of V m' manufacturing is greatly reduced.Other advantages will appearupon reading the following descriptipn. r

In describingthis invention reference is had to the accompanyingdrawings in which 13' like characters designate corresponding parts inall the Views. e I

Figure 1 is an inverted plan view show-- ing a portion of the trim withcontiguous portion of the cabinetpartly in secton.

zo Figure 2 is a view in elevation of the clamping means shown inoperative position securing a portion of the trim to the contiguousportion of the cabinet. F igure 3 is a view in elevation similar to Figure 2 with the fastening means in inoperative position. v

1 designates the side walls of the .panel board cabinet or boX and 2 aflange formed on the front of the box by the walls being turnedinwardly, which flange provides a support for the trim 3. The trim inthis instance corresponds to the cover of a box. 'The fastening 'meanshere shown is carried by the cover or trim which is secured in positionafter the box or cabinet is placed in operated position, generally inthe wall-s or partitions of'buildings.` V j 4 designates an S-shapedsupport with a central elongated portion formed at right' 40 anglesto'the parallel end portions. One end portion is Secured to'the underside oftthe trim, preferably'by spot weldng, while theother is drilledto receive the end of a screw 5. 6 is a jaw or clamping member for-medfrom a fiat piece of steel by bending over the e sides forming a channelwith a back portion 7 and side railsB. r

The siderails are shaped similar to'a jack 'knife *blade with the heelportions drilled and threaded to receive the screw 5.

v wise direction; ;the jaWG iscausedto move in vided 'on the end portionof the rupper side In assembling the device; one endportion of thesupport 4 is .spot welded to thetrim in a predetermined position. {Thescrew 5 is then passed, through a hole in the trim, also at apredetermined position in relation to the support 4 so that the screw 5will passf through the hole formed in .the opposite end portion` ofthe'support After the screw 5 is passed throughthe hole in the trim 3,it is threaded' through the heel ,portions of the jaws 6 and then'passed throughthe h'ole in the end portionof the support 4 and head; edover, as shown at 9, sothat the screw-'cannot get` out of place and"cause trouble and delay whenthe trim is being Secured in position on:the lirontside. of the bOX or cabinet p 7 I :j

'Upon turning' of the screw 5 in, a clockr the` same direction as thescrew until` the rear edge; portion 10` contacts with :the-"centralportion of the support 4, at ,which time,vthe

outerend of the jaw assumes an operative pos'ition under the flangebfthe 'boxor .cabinet. i a l i r v I ,'ontinuedturning of the screw causes7 .the jaw (if tomove toward 'thetrim and' eventually engage with thefiange 2 ofthe boxzor cabinet, .th us clamping the, .trim 3 tightly onthe front of the cabinet. Generally. the screw 5 will 'fitthe threaidedpor tion of theiside rails 8 of the jaw 6 tight' 'enoughfto causethe jawto move with the screw until ?stopped by contact with the cen-` tralportion of the support 4. However,-to,

prevent' the jawfrom becoming loose, the screw 5 is provided withtension means as shown by spring'10 'which holdsthe' jaw in friction'alcontact with the screw throughout' its entire length. Tocompensate forefiective, a boss 'or raised portion ll is pro:

jaw member 6 in the same direction the 'the thickness of the spring whencompressed, i j and also to renderthe clamping means more rall ,ofthejaw 6 whichraisedportion coactsis e 'I jaw assuming a position outfrom under the fiange 2. The trim is then placed upon the front of thebox or cabinet and by merely turning the screw 5 in clockwise direction,the end of the 6 is swung under the fiange 2 and by continued movementof the screw, the jaw is caused to slidably engage with the centralportion of the support 4 and eventually coact against thefiange 2 ashere totore described NVhat we claim is:

1. A clamp comprising a support, a screw Secured to said support toprevent endwise movement of the screw, a jaw threaded on the screw, andmeans to limit the rotary movement of the jaw by contact with thesupport.

2. The conibnation of two parts to be clamped together, 'a clampcomprising a support carried by one part, a screw eXtending I throughsaid part and into engagement with I p the support, and means forholding the screw i from endwise movement, a jaw threaded on the screwandi slidably. engaging the support and means for holding the jaw insufiicient frictional contact with the screw whereby the jaw is rotatedwith the screw until stopped by contact with the support.

3. The combination of a boX and a cover to be clamped together, asupport carried by the cover on the inner side thereof and dependinginto the box in a general direction parallel to a side wallof the box, ascrew extending through the cover substantially parallel to thedepending portion 'of the support and connected to the support at itsinner end to hold the screw froni displa cement, a jaw threaded on thescrew, the screw eXtend ing through, the jaw near one end thereof. andsaid end slidably engaging the support and having a shoulder to coactwith thesupport 'when the jaw has been turned t'oiposi- %on in operativerelaton to the wall of the ox.

In testimony whereof, we have hereunto signed our names at Syraeuse, inthe county of Onondaga and. State of New York, ,this 25th day ofJanuary, 1929. i i i EDWIN A. OLLEY. DANIEL, B. WINTER'. i
